POLISHIN G MACHINE.

Application led November 8, 1926. Serial No. 147,164.

The object of the invention is to produce a machine that is simple in construction, practical, and adapted to be used for the purpose of polishing waxed floors, but may be used lfor many other purposes where a polishing machine can be used.

This machine is constructed and designed to be operated by means of a small electric motor, the parts in motion being protected by a suitable housing, or cover, attached to the sides of the frame, and asN the machine is moved over'the floor that has been waxed, thevpolishing roller revolves ata high rate of speed, which crea-tes all the friction necessary to producel the most brilliant polish, in a very brief amount of time.

In the drawings and figures of reference a pulleywheel broken away, exposing the ends of thepad and the small wire rod in one end of the pad.

Fig. 3 is a perspective view of a portion of the polishing roller, showing a portion cut away, exposing the construction in section'.

Fig. 4 is a side view of one side of the housing looking toward the inner surface.

Fig. 5 is a top plan view of the housing.

Reference now being had to the drawing by numerals, in which like figures indicate like parts throughout the several. views: 1 shows the main frame to which other parts are attached, and designed to carry all other parts of the machine; 2 represents the arm extension of the frame, which carries the motor; 3 represents the motor, placed in the arm and held in place with the screws 4 and 5; 6 represents the wires connected to the motor; 7 shows the screw extending from thearm, to which the handle 8 is attached; 9 represents the shaft that passes through the metal cylinder; 10 .represents the cylinder, with the perforations shown at 11; the two pulley Wheels attached to the shaft are shownv at 12 and 13 and held in place with lock nuts as shown at 14; the polishing pad placed around the cylinder is shown at 15, the bevel cut ends of the pad are shown at 16, with one end overlapping the other end; 17 shows the wire rod, which passes through the pad near the overlapping end of the pad, the ends of the wire rod beingilocked in the small holes in the pulley wheels, as shown at 18; pulley wheels 19 and 20 are shown attached to the endsof the motor shaft; 21 and 22 show the belts passing around the pulley wheels at the ends of the polishing roller and the wheels on the ends of the motor shaft; 23` represents the bearings, in which the ends of the shaft in the polishing roller are journaled; 24 shows one of the clamps bolted to the frame to hold the bearings; 25 and 26 show the two side parts of the housing; 27 is a flat pla-te connected with the two sides of the housing and covers the open space between the polishing roller and the motor; the housing is attached to the sides of the frame with screws passing through the holes at 28 and 29,7in the sides of the housing, and screwed into corresponding screw holes in the sides of the frame,

shofwn at 30 and 31; the in Figml show the position when attached -to the frame.

The principal features in this invention are the assembly and operation of the parts as herein shown, which produce the best results desired. The, means which I employ for this purpose consists in asoft pliable ad attached to a perforated metal cylin er, formed from a piece of sheet metal. The perforations are punched through the metal while it is iat, then it is rolled to the form of a cylinder, the edges being soldered, or the/edges may be crimped together, with the rough jagged points of the' perforations on the outer surface of the cylinder. The sharp points penetrating the inner surface of the pad, prevent the pad from slipping. The padmay be cemented to the cylinder, and as the perforations help to hold the cement there is no chance for the pad to slip in any manner.

The ends of the. pad are cut with a lon bevel, in such a manner that one end is'wel 'overlapped on the other end, the ends being cemented, pressed together, and locked b means of a small wire rod passing throu the pad near the overlapping end, with t e ends of the rod inserted in suitable depressions in the large pulley wheels, binding the ends of the pad close together.

dotted lines 32, of the housing The two large pulley wheels are attached to a shaft that passes through the cylinder, the pulley wheels fitting close over and against the ends of the cylinder; the shaft, cylinder, and pulley wheels being firmly bound together with lock nuts on each end of the shaft and screwed up tight against the pulley wheels, in such a manner that the pulley Wheels, shaft, and polishing roller all revolve together as one, with the same motion.

All the working parts at each side being duplicate in construction; the shaft being yjournaled in suitable bearings attached to the main frame with clamps underneath, bolted to the frame.

The main frame is designed to carry all other parts of the machine, with an arm, which is a part of the frame, extending to the rear to carry the electric motor, the arm being curved to fit close to and a little more than half way around the motor, which is slipped into the arm endwise and held iirlnly in place with screws passing through the arm underneath. The main frame'fconsists of the front rectangular part which carries the polishing roller, the arm extending to the rear to carry the motor, with the screw extending from the arm, to which a suitable handle is attached to move the machine over the floor.

The polishing roller is operated by belts passing around the pulley wheels on the ends of the roller and around the wheels attached to the shaft in the motor, the wires leading from the motor can be connected with any incandescent light socket, or any other suitable connection; the motion of the motor and polishing roller being controlled by a switch attached at a convenient place on the handle.

In using the machine for the purpose of polishing a waxed Iioor, after the roper wire connections are adjusted, the e ectric current is switched to the motor, and as the polisher is moved over the floor, the padded polishing roller revolving at high speed, produces the most brilliant polish desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a roller for `'a polishing machine, a perforated cylinder, a suitable polishing pad placed around the cylinder, a locking rod passing through the pad, with means foilocking the rod to bind the ends of the polishing pad together.

2. In a roller for a polishing machine, the combination of a pad with bevel cut ends placed around a perforated cylinder, one end of the pad overlapping the other end, a rod passing through the pad near the overlapping end, to bind the two ends of the pad together.

3. In a polishing machine, the combination of a perforated cylinder, a polishing pad with the ends cut beveled placed around the cylinder, one end of the pad overlapping the other end, pulley wheels at the ends of the cylinder, a shaft passing through the cylinder, with the pulley Wheels attached thereto, locking nuts on each end of the shaft to bind the pulley wheels, cylinder and shaft together, a binding rod passing through the pad near the overlapping end,

with suitable means Within the pulley Wheels to lock the rod.

4. In a polishing machine, the combination of a polishing roller, including a perforated cylinder, a polishing pad with bevel cut ends, placed around the cylinder, a locking rod passing through the pad, a shaft, pulley wheels attached to the shaft, locking nuts attached to the shaft, binding the shaft, pulley wheels and cylinder together as one.

5. In a polishing machine, including a frame, the combination of a polishing roller with the frame, said roller including a perforated cylinder, a :polishing pad attached to the cylinder, a locking rod passing through the pad, a shaft passlng through the cylinder, journaled in bearings attached to the frame, pulley Wheels attached to the shaft, locking nuts attached to the shaft, binding the shaft` pulley wheels and cylinder together, with means connected therewith to operate the polisher.
